Notes:
1. All parameters representing voltages are measured with respect to GND unless otherwise specified.
2. To ensure targeted reliability standards are met across ambient and junction operating temperatures, Microsemi
recommends that the user follow best design practices using Microsemi’s timing and power simulation tools.
3. The ranges given here are for power supplies only. The recommended input voltage ranges specific to each I/O
4. All IGLOO devices (V5 and V2) must be programmed with the VCC core voltage at 1.5 V. Applications using the V2
devices powered by 1.2 V supply must switch the core supply to 1.5 V for in-system programming.
5. For IGLOO V5 devices
6. For IGLOO V2 devices only, operating at VCCI
VCC.
7. VPUMP can be left floating during operation (not programming mode).
for further information.
9. VMV pins must be connected to the corresponding VCCI pins. See the "Pin Descriptions" chapter of the IGLOO FPGA 10. 3.3 V wide range is compliant to the JESD-8B specification and supports 3.0 V VCCI operation.
